hum,
I mean my jsp is built dynamically.. so when my select box is set to "1",
my jsp is made with 4 fields.
But if my select box is set to "2", "3" or "4". my JSP page is made with 3
new fields.
And I think that "hide" means present but not visible.. and "not display"
means not present in the page.
I hope you'll understand, I'm sorry for my poor english.
SO, have a look at my jsp, it could be more comprehensive:
<html:select property="subscriptionType" styleId="inscrit"
styleClass="form" onchange="ChangeUrl(this.form)">
<html:option value="1"><bean:message key="
inscription.particulier"/></html:option>
<html:option value="2"><bean:message key="
inscription.membre.entreprise"/></html:option>
<html:option value="3"><bean:message key="
inscription.professionnel"/></html:option>
<html:option value="4"><bean:message key="
inscription.elu"/></html:option>
</html:select></td>
</tr>
<% String val = new String("1") ; %>
<logic:notEqual name="startSubscriptionForm"
property="subscriptionType" value="<%=val%>">
<html:text property="enterpriseName" name="S_ENTREP"
styleId="nomentreprise" styleClass="form" size="20" value=""/>
<html:text property="legalRepresentant" name="S_REPRES"
styleId="representant" styleClass="form" size="20"
<html:text property="siren" styleId="siren" name="S_SIREN"
styleClass="form2" size="10" maxlength="14" value="" /></td>
</logic:notEqual>
I just want those 3 fields (enterpriseName, legalRepresentant and siren) to
be required if select box != 1.

Dear Jeremy ..
what do you mean with "should I "hide" fields rather than "not
display" fields.. ??",
"hide" and "not display" are the same things isn't it :-)
if you're expect the validwhen to manage hide and unhide HTML object,
validwhen couldn't do such a thing.
=====
Taken from struts doc :
[Since Struts 1.2.0] A frequent requirement in validation design is
to validate one field against another (for example, if you have asked
the user to type in a password twice for confirmation, to make sure
that the values match.) In addition, there are fields in a form that
may only be required if other fields have certain values. The
validwhen validation rule is designed to handle these cases.
=====
Otherwise, to manage hide and unhide HTML Object which is generated by
Struts, you can create your own javascript function to hide/unhide the
object, and then call the function manually using OnChange property in
your select tag.
